[Coco] SCSISYS question

[Bob Devries]

>From the SCSISYS manual:
IT.STP
Bits 7-2 = partition
bits 1-0 MPI slot
IT.TYP
bit 7 = hard disk
bit 6 = fudge LSN0
bits 3-5 = cluster size
bit 2 = 6309 flag
Bit 0-1 = sector size
IT.DNS
bit 7 = 512 flag
bit 5-6 = LUN
bit 4 = error type
bit 3 = no cache
bit 2 = no turbo
bit 0-1 = SCSI ID

So, my H1 descriptor is SCSI ID 1 and hence IT.DNS=$81
